What a fomoback is
A coin launched here charges 4% on its own trades, keeps the money in a contract nobody can withdraw from, and spends it buying itself back the moment somebody who holds the coin publishes a thesis about it.
The mechanic is not new. Two sites shipped it before us. What is new is that the fee wallet is a contract with no owner, the split cannot be changed after deploy, anyone can fire a run, and the person who wrote the thesis is paid.
Everything on this page is a constant in the vault contract. If one of them changes in the code it changes here in the same commit.
How a run fires
- ·Somebody trades the coin. 4% comes off the quote leg, both directions.
- ·The fee lands in that coin's BackVault. The recipient is fixed at creation.
- ·A holder publishes a thesis in the social app. No signing, no gas.
- ·The attester signs a typed receipt: this text, this author, this wallet, this time, this coin.
- ·Anyone calls run(receipt). The contract checks the receipt, the holding, the cooldown, the budget and the price impact.
- ·One transaction buys, burns, pays the writer, pays the caller, and records the receipt hash.
Underneath the trigger there is a clock. If nobody writes anything for 20 minutes, any caller can fire a clock-driven run instead, so a coin earning fees in silence still deploys them.
The split
- Burn
- 60% — buys the coin on its own venue and destroys everything it buys
- Writer
- 30% — the person whose thesis fired the run
- Caller
- 5% — whoever paid the gas to send the transaction
- Protocol
- 5% — routed to the $BACK vault, which buys and burns $BACK
These four are constructor arguments. There is no setter function anywhere in the contract. A launcher cannot change them and neither can we.
How the writer is paid
The writer's 30% is scaled by how much of the coin they hold, measured at the moment the thesis was published.
writerPay = runBudget × 0.30 × min(holdingShare, 2%) / 2%- ·Hold 2% or more of supply, and you take the full 30%.
- ·Hold 1%, and you take half of it.
- ·Hold nothing, and the receipt is rejected before it costs anyone gas.
The contract re-checks your balance at execution and uses the lower of the two figures. A writer who sold between publishing and payout is paid on what they still hold, not on what they claimed.
Anything a writer does not qualify for stays in the vault and goes to the burn side of the next run. It is never swept to a treasury.
Every gate and figure
- Creator fee
- 4%, every buy and every sell, both directions
- Clock floor
- 20 minutes — what the time term is measured against
- Cooldown
- 10 minutes — hard floor on clock-driven runs
- Writer cooldown
- 6 hours per writer per coin
- Impact cap
- 2% — the most of the venue's reserve one run may move
- Counted holding cap
- 2% of supply
- Budget floor
- a run must be worth more than the gas it costs
- Replay guard
- each receipt hash pays exactly once, ever
- Supply
- 1,000,000,000
- Graduation
- 4.2 ETH into the curve
The trust boundary
A thesis is published off chain, and no contract can read a social feed. So there is exactly one trusted component. This is the honest description of it.
The attester can decide which receipts get signed, and therefore when runs happen. It cannot move a single wei out of any vault, change the split or the caps, pay an address that does not hold the coin, pay the same receipt twice, or stop anyone else firing a clock-driven run.
Worst case with a fully malicious attester: fees the coin already earned get spent buying that coin back sooner than they otherwise would, bounded by the same impact cap, with 30% going to holders who were named. That is the entire blast radius.
If the attester goes dark, clock runs continue and writers can self-claim from their own linked wallet after a challenge window. Nothing is stranded, because nothing was ever in our custody.
Launching a coin
- ·Fill in name, symbol, image and description.
- ·The app computes your vault address before anything is sent, and shows it to you.
- ·One signature from your own wallet deploys the vault, launches the coin, and names the vault as fee recipient, atomically.
- ·Fund the vault's gas float once. It is never spent on a buyback.
We never ask for a private key. There is no field on any route of this site that accepts one. If a site asks you to paste 64 hex characters into a web page, close the tab.
What this does not do
- ·It is not free money. The fee comes out of the people trading the coin and goes back into the same market.
- ·A buyback is not a price floor. A coin can only ever spend what it earned in fees.
- ·A thesis is not a prediction. The contract counts theses. It does not read them.
- ·No volume means no fees, no runs and no payouts. The mechanism amplifies activity, it does not create it.
